Suggestion: a flag for enabling propagation of the exit code

[aqjune]

Hi,

ledit does not propagate the exit code from the invoked process:

$ ledit ocaml
OCaml version 4.14.0
Enter #help;; for help.

# exit 1;;
$ echo $?
0

This behavior is different from the behavior of another line editing tool rlwrap:

$ rlwrap ocaml
OCaml version 4.14.0
Enter #help;; for help.

exit 1;;
$ echo $?
1

I think it would be nice if there is a commandline option in ledit that propagates the exit code of the process that was called. :)
